VSP技术在缅甸石油勘探区块的应用
|
摘要
缅甸中部曼德勒市以西某石油勘探区块勘探程度低,面临许多急需解决的地质问题。A-1井是中国石化在该区块开钻的第1口探井,2008年油气测试获得了较好的油气显示。在A-1井首次采集了零偏和非零偏VSP资料,进行了初至拾取、三分量旋转、波场分离、反射波成像等处理;综合利用A-1井的测井、钻井、VSP、二维地面地震等资料,标定了该区块A-1井处地震反射波组的地质属性,确定了主断层的断点位置,建立了泊松比参数与主力含气层段、非出气层段等的特征关系。VSP技术的应用在该区块的油气勘探中发挥了积极的作用。
Well A-1 is the first exploration well drilled by SINOPEC in Myanmar.It turned out promising oil show in testing for oil.Both zero-offset and offset VSP data were acquired and they were processed by series of steps including first arrival pickup,3-component rotation;wavefield separation,and reflection imaging.By jointly using logging,drilling,VSP and 2-D seismic data,we tied main seismic horizons to geology,determined the location of major fault PA in well A-1,and established the correlation of gas-bearing and non-gas-bearing interval with Poisson's ratio.
